Abstract

An effective de-fluorination method is developed to modify CF_x cathodes through a hydrothermal process and it greatly improves the capacity performance and rate capability of CF_x by removal of surface ionic transport barriers. A capacity of 500 mA h g⁻¹ and a maximum power density of 48 400 W kg⁻¹ were achieved at an ultrafast rate of 30 C.
